A kind of preparation method of modified polypropylene fiber

Abstract

The invention discloses a method for preparing modified polypropylene fiber. The method for preparing modified polypropylene fiber adopts the following preparation equipment. The modified polypropylene fiber preparation equipment includes a solution box, a support plate, an oscillating device, a wire feeding device, Drying unit and winding unit. The method for preparing modified polypropylene fibers using the above-mentioned modified polypropylene fiber preparation equipment includes the following steps: S1, installation of polypropylene fiber coils; S2, polypropylene fiber transportation; S3, shock modification of polypropylene fibers; S4, modification Dry polypropylene fibers. The invention can effectively treat the polypropylene fibers when they react in the modified solution, so that the polypropylene fibers are difficult to entangle with each other, ensuring normal production, and at the same time, sufficient contact between the polypropylene fibers and the modified solution can be achieved. Contact reaction can effectively improve the quality of the produced modified polypropylene fiber.

Description

technical field [0001] The invention relates to the technical field of fiber preparation, in particular to a method for preparing modified polypropylene fibers. Background technique [0002] Polypropylene fiber is a synthetic fiber spun from isotactic polypropylene obtained by propylene polymerization. Melt blown non-woven fabric, etc. Polypropylene long fibers can be divided into ordinary long fibers and fine denier long fibers, with a single filament size of ≤2.2 dtex, which can be used to produce filament products for clothing, decoration and some industries. Polypropylene fine denier long fibers have good luster, soft hand feeling, good drapability and low density. They are suitable for the knitting industry. Ideal material for high-end sportswear, T-shirts and more. Polypropylene fiber has many excellent properties, but it also has disadvantages such as strong waxy feeling, hard hand feeling, difficult dyeing, and easy accumulation of static electricity. Therefore, ...

Problems solved by technology

[0003] However, the traditional modified polypropylene fiber preparation equipment has the following problems when preparing modified polypropylene fiber fibers: 1. When the traditional modified polypropylene fiber preparation equipment is preparing modified polypropylene fibers, the presence of multiple groups of polypropylene fibers If the reaction is carried out in the modified solution, it is easy to entangle and cause the polypropylene fiber to be damaged and waste materials; 2. When the traditional modified polypropylene fiber preparation equipment is used to prepare the modified polypropylene fiber, the polypropylene fiber cannot be fully mixed with the modified solution. reaction, resulting in poor quality of modified polypropylene
